摘要：

腈纶废水对微生物活性具有不良影响, 采用铁炭微电解―混凝沉淀―MBBR工艺对其进行处理。通过正交试验, 探索了铁炭微电解预处理腈纶废水的最佳工艺条件;再以MBBR为生物反应器, 进一步处理经过铁炭微电解预处理的腈纶废水。结果表明, 最终出水COD可稳定至100 mg/L以下, 氨氮接近15 mg/L。该工艺是处理腈纶废水的有效方法。

Abstract:

Acrylic fiber wastewater has adverse effects on microbial activity. Ferric-carbon micro-electrolysis-coagulation-MBBR process has been used for treating it. The optimum technical conditions for the pretreatment of acrylic fiber wastewater by ferric-carbon micro-electrolysis process are explored by orthogonal test. Then, the pretreated acrylic fiber wastewater is further treated with MBBR as a biological reactor. The results show that the final effluent COD is stabilized below 100 mg/L and ammonia-nitrogen around 15 mg/L. The process is an effective way for treating acrylic fiber wastewater.

Key words: acrylic fiber wastewater, ferric-carbon micro-electrolysis, moving bed biofilm reactor
